Ipod Frozen on restart Screen and freezes on diagnostics

macrumors newbie

Hey. I have an 80GB Ipod classic. I recently updated my Itunes and my Ipod software.
I restarted the computer and then my Ipod starts acting weird and then I plug it in and it will not do anything. I restart the Ipod and it freezes on the restart apple screen. I went into diagnostics and it now says please plug in FW on about the 4th diagnostics test. What do i do?
any help is greatly appreciated. This ipod is my life
